Eliminate Risk of Failure with US Green Building Council LEED-AP-Homes Exam Dumps

The LEED for Homes Rating System (v4) addresses shower compartments in the Water Efficiency (WE) Credit: Indoor Water Use, where the size and number of showerheads impact water use calculations.

According to the LEED Reference Guide for Homes Design and Construction (v4):

WE Credit: Indoor Water Use (1--6 points)

A shower compartment is defined as an enclosed area with a floor area of no more than 2,500 in (1.6 m), where all fixtures (e.g., multiple showerheads) count as a single fixture for water use calculations. Compartments larger than 2,500 in are considered multiple compartments, and multiple showerheads in such cases are not allowed for LEED compliance to ensure water efficiency.

Source: LEED Reference Guide for Homes Design and Construction, v4, Water Efficiency Credit: Indoor Water Use, p. 96.

The LEED v4.1 Residential BD+C rating system confirms:

WE Credit: Indoor Water Use

For shower compartments exceeding 2,500 in (1.6 m), multiple showerheads are not permitted to maintain water efficiency goals. Each compartment must be treated separately if applicable, but large compartments cannot have multiple heads.

Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.

The shower compartment is 3,750 in (2.4 m), exceeding the 2,500 in limit. Therefore, multiple showerheads are not allowed (Option C), as LEED restricts multiple heads in oversized compartments to ensure water efficiency.

Why not the other options?

A . The flow rates are added to total 3.0 gpm (11.2 lpm): This applies to compartments 2,500 in, not larger ones like 3,750 in.

B . The flow rate is calculated as two separate compartments of 1.5 gpm (5.6 lpm): The compartment is one unit, and multiple heads are not allowed, not treated as separate compartments.

D . Shower compartment size does not affect shower head flow rates for LEED compliance: Compartment size directly affects whether multiple heads are allowed.

The LEED AP Homes Candidate Handbook emphasizes WE credits, including showerhead calculations, and references the LEED Reference Guide for Homes Design and Construction as a key resource. The exam is based on LEED v4, ensuring the relevance of compartment size restrictions.

The LEED for Homes Rating System (v4) includes the Sustainable Sites (SS) Credit: Nontoxic Pest Control, which awards points for physical or nontoxic strategies to prevent pest entry, such as termites, without relying on chemical treatments unless specifically allowed.

According to the LEED Reference Guide for Homes Design and Construction (v4):

SS Credit: Nontoxic Pest Control (1 point)

Use treated wood (e.g., pressure-treated or borate-treated) for all wood-to-concrete connections to prevent termite damage in a way that minimizes environmental impact compared to broad chemical treatments. This is considered a nontoxic or low-toxicity strategy for pest control.

Source: LEED Reference Guide for Homes Design and Construction, v4, Sustainable Sites Credit: Nontoxic Pest Control, p. 82.

The LEED v4.1 Residential BD+C rating system confirms:

SS Credit: Nontoxic Pest Control

Using treated wood for wood-to-concrete connections is an acceptable strategy to earn points by preventing pest access while minimizing chemical use.

Source: LEED v4.1 Residential BD+C, Credit Library, accessed via LEED Online.

The correct answer is use treated wood for all wood-to-concrete connections (Option C), as this is a recognized nontoxic pest control strategy for the credit.

Why not the other options?

A . Treat all material with a borate product: Treating all materials is overly broad and may not be considered nontoxic due to excessive chemical use.

B . Install landscaping within 24 in. (0.6 m) of home: This may increase pest access, contradicting the credit's intent.

D . Treat all wood framing with a borate product to a minimum of 3 ft. (0.9 m) below foundation: This is not a standard strategy and may involve excessive chemical use, not aligning with nontoxic goals.

The LEED AP Homes Candidate Handbook emphasizes SS credits, including nontoxic pest control, and references the LEED Reference Guide for Homes Design and Construction as a key resource. The exam is based on LEED v4, ensuring the relevance of treated wood strategies.

The LEED for Homes Rating System (v4) addresses rainwater harvesting in the Sustainable Sites (SS) Credit: Rainwater Management, which aims to reduce runoff and its environmental impacts, particularly in areas with significant rainfall events.

According to the LEED Reference Guide for Homes Design and Construction (v4):

SS Credit: Rainwater Management (1--3 points)

Rainwater harvesting systems (e.g., rain barrels, cisterns) capture and store rainwater, reducing runoff volume and mitigating on-site erosion, especially during substantial rainfall spikes, by preventing excessive water flow across the site.

Source: LEED Reference Guide for Homes Design and Construction, v4, Sustainable Sites Credit: Rainwater Management, p. 76.

The LEED v4.1 Residential BD+C rating system confirms:

SS Credit: Rainwater Management

A key benefit of rainwater harvesting is mitigating on-site erosion by capturing runoff, particularly in areas with heavy rainfall, reducing soil displacement and environmental damage.

Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.

The correct answer is mitigates on-site erosion (Option A), as rainwater harvesting reduces runoff, preventing erosion during rainfall spikes.

Why not the other options?

B . Helps to maintain required firewater levels: Rainwater harvesting is typically for non-potable uses like irrigation, not firewater systems.

C . Little-to-no benefit since precipitation is seasonal: Rainwater harvesting is highly beneficial during rainfall spikes, storing water for later use.

D . Eliminates the need for low-flow plumbing fixtures: Rainwater harvesting addresses outdoor water, not indoor plumbing fixtures.

The LEED AP Homes Candidate Handbook emphasizes SS credits, including rainwater management, and references the LEED Reference Guide for Homes Design and Construction as a key resource. The exam is based on LEED v4, ensuring the relevance of erosion mitigation.

The LEED for Homes Rating System (v4) awards points for the Materials and Resources (MR) Credit: Environmentally Preferable Products when using certified lumber, specifically Forest Stewardship Council (FSC)-certified wood, which contributes to the required percentage of material cost.

According to the LEED Reference Guide for Homes Design and Construction (v4):

MR Credit: Environmentally Preferable Products (1--4 points)

Use FSC-certified wood for at least 25% (1 point), 50% (2 points), or 90% (3--4 points) by cost of the total materials. For specific material categories like roof sheathing, at least 90% of the component (by cost) must be FSC-certified to significantly contribute to the credit.

Source: LEED Reference Guide for Homes Design and Construction, v4, Materials and Resources Credit: Environmentally Preferable Products, p. 160--161.

The LEED v4.1 Residential BD+C rating system confirms:

MR Credit: Environmentally Preferable Products

Points are awarded for FSC-certified lumber if it constitutes at least 90% of a specific component like roof sheathing (by cost) to meet higher point thresholds (e.g., 3--4 points). Certified lumber is not a prerequisite; it contributes to the credit.

Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.

The correct answer is if the certified content is greater than 90% (Option B), as this ensures the roof sheathing significantly contributes to the credit's material cost threshold for points.

Why not the other options?

A . If the certified content is greater than 45%: This is below the 90% threshold for significant contribution from a single component like roof sheathing.

C . If the certified wood is sourced from a 600 mi. (966 km) radius: Local sourcing (within 100 miles) is relevant for Option 1: Local Production, not FSC certification.

D . No points are earned because certified lumber is a prerequisite: Certified lumber is not a prerequisite; MR Prerequisite: Certified Tropical Wood applies only to tropical wood, not all lumber.

The LEED AP Homes Candidate Handbook emphasizes MR credits, including certified lumber, and references the LEED Reference Guide for Homes Design and Construction as a key resource. The exam is based on LEED v4, ensuring the relevance of FSC certification thresholds.

The LEED for Homes Rating System (v4) includes the Water Efficiency (WE) Credit: Outdoor Water Use, which awards points based on the ratio of turf grass (high water use) to native or adapted plants (low water use) in the softscape to reduce irrigation needs.

According to the LEED Reference Guide for Homes Design and Construction (v4):

WE Credit: Outdoor Water Use (1--4 points)

To achieve 3 points, the softscape must have less than 20% turf grass and more than 75% native or adapted plants, calculated by area.

Source: LEED Reference Guide for Homes Design and Construction, v4, Water Efficiency Credit: Outdoor Water Use, p. 98--99.

The LEED v4.1 Residential BD+C rating system confirms:

WE Credit: Outdoor Water Use

For 3 points, the turf grass area must be less than 20% of the total softscape, and the native or adapted plant area must exceed 75%.

Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.

Calculation:

Total softscape area: 57,500 ft (5,342 m).

Turf grass area: 8,000 ft (743 m).

Turf grass percentage: (8,000 57,500) 100 = 13.91% (< 20%, meets requirement).

Minimum native or adapted plant area for 3 points: > 75% of 57,500 ft = 0.75 57,500 = 43,125 ft.

Compare options:

A . 38,967 ft (3,620 m): 38,967 57,500 = 67.77% (< 75%, does not meet).

B . 39,355 ft (3,656 m): 39,355 57,500 = 68.44% (< 75%, does not meet).

C . 43,126 ft (4,007 m): 43,126 57,500 = 75.00% (meets > 75% requirement).

D . 2,784 ft (259 m): 2,784 57,500 = 4.84% (far below 75%, does not meet).

The correct answer is 43,126 ft (4,007 m) of native or adapted plant area (Option C), as it meets the minimum requirement for 3 points.
